Objective To explore clinical characteristics and the perinatal effects of multiple systems in pre-pregnancy obesity patients with early-onset preeclampsia. Methods A total of 111 cases with early-onset preeclampsia in our Inpatient Obstetric Department were reviewed in this study. According to pre-pregnancy body mass index (BMI), patients were divided into normal before pregnancy group (BMI<28 kg/m2, n=56) and obese before pregnancy group (BMI≥28 kg/m2, n=55) . The body weight, BMI, weight gain during pregnancy, risk factors, clinical features, and clinical features of neonatal index were compared between two groups. The correlation between maternal and neonatal indexes and glucose and lipid indexes were compared. Results Obese before pregnancy was more prone to blood concentration and disorders of lipid metabolism. The serum levels of lipid, glycosylated hemoglobin (HbA1c), hematocrit, platelet and fibrinogen were significantly higher in obese before pregnancy group than than those of normal group. The induced neonatal acidosis and other organ damage, newborn Apgar score, pH, glucose were significantly lower in obese before pregnancy group than those of normal group. The residual alkali (BE), lactic acid (LAC), creatine kinase (CK) and creatine kinase (CKMB) were higher in obese before pregnancy group than those of normal before pregnancy group. Correlation analysis showed that maternal low density lipoprotein cholesterol (LDL-C), total cholesterol (TC), three acyl glycerol (TG) and HbA 1c were negatively correlated with neonatal Apgar score and pH, and which were positively correlated with neonatal LAC and CKMB. Both differences were significant (P<0.05 or P<0.01). Conclusion The dyslipidaemia in early onset preeclampsia in obesity patients before pregnancy is closely related with maternal and perinatal outcomes.

The diaphyseal nutrient foramina were examined in 246 tibia and 212 fibula from complete sets of Chinese adult skeleton collection.The length and diameter of these bones were also measured.The number,position and orientation of the nutrient foramina were more variable in fibula than in tibia. Though the position of the nutrient foramina of the shaft of these bones were vari- able,however there was a restricted area in which most of the foramina were located. The nutrient foramina of the tibia usually situated on the posterior surface near the junction between the upper and middle thirds of its length,and that of the fibula was on the posterior or medial surface within the upper portion of the middle third segment. The nutrient artery to tibia and fibula were dissected and observed in 100 cases. The nutrient artery to tibia may have various sources of origin,it may arise from the posterior tibial,anterior tibial,and fibular arteries or directly from the popliteal artery. It has a larger calibre and runs over a longer course.The nutrient artery to fibula is relatively small and short,and all originate from the fibular artery. Certain practical applications of the arteries are briefly discussed.

Some anatomical aspects in application for the vein catheterization on the subclavian and other veins of the neck have been studied on 85 cadavers in Chinese adults.The subclavian vein measures 1.16cm in diameter and 3.76 cm in length. It lies 2 cm deep under the skin and muscles in the infraclavicular region. The angle between the vein and the clavicle is 38?. It usually lies behind the medial third of the clavicle and is separated from the subclavian artery, brachial plexus and the cupula of the pleura by the anterior scalenus muscle. This muscle is 1.19 cm in width and 0.37 cm in thickness, much thinner than the thickness mentioned in the previous literature. The distance from the origin of the subclavian vein to the opening of the superior vena cava into the right atrium is 13.85 cm on the right, and 16.36 cm on the left.The diameter of the internal jugular vein and its topographical relationship to the origin of the sternocleidomastoid muscle were also observed. The internal jugular vein is 1.26 cm in diameter, and lies under the clavicular head of the sternocleidomastoid muscle in 58.75%, between the two heads of this muscle in 41.25%.The external jugular vein measures 0.63cm in diameter, but its location and termination are more variable.The application of these data in vein catheterization was also discussed in this article.

Popliteal fossa dissections were performed on two hundred adult extremities and the patterns of the deep venous system were observed. Three general types were established for the popliteal vein and its branches. Single large trunk representing the popliteal vein at the level of the knee joint occurs only in 32.00％, two venous trunks at this level in 65.50％ and three venous trunks in 2.50％. Furthermore, considerable variations of the formation of popliteal veins were found. The patterns of popliteal vein were divided into three main types and eleven subtypes. Type Ⅱa occurs most frequently (41.50％). The size of each vein of the deep venous system was measured. The average calibre of the single popliteal vein is 6.89mm (ranging between 4.0-11.5 mm). The veins from the gastrocnemius muscle join the single or the two popliteal trunks respectively. The veins of the soleus muscle drain into the peroneal and posterior tibial veins. The short saphenous vein typically terminates in the popliteal vein. Variations in its termination were described.

The contents of dopamine (DA) and its metabolites, homovanillic acid (HVA) and 3,4-dihydroxyphenyl acetic acid(DOPAC), in both striata were determined with HPLC-EC technique in each of 28 albino rats, which were divided into 3 groups (bilateral lesioned, unilateral lesioned and healthy control groups). Among the unilateral lesioned rats, three indices such as DA, HVA/DA and DOPAC/DA in the lesioned striata were 22.27％, 420.00％ and 199.75％ of those of the intact striata, respectively. This suggests that there may be an enhanced compensatory DA release in the striatum ipsilateral to the lesion of the rat. Having compared the lesioned striata of unilateral lesioned rats with those of bilateral lesioned animals, and the intact striata of unilateral lesioned rats with those of the control ones, we did not find any significant differences in DA, HVA/DA or DOPAC/DA. The result implies that the compensatory DA release in the lesioned striatum probably accounts for the mechanism of the ipsilateral nigrostriatal system, not for the crossed nigrostriatal fibers.

Objective To observe the iodine state of patients with autoimmunity thyroid disease(AITD) in Shaanxi province,and to discuss the relationship between the metabolism of iodine and the occurrance,development and prognosis of AITD.Methods A total of 388 cases were collected,among whom 283 were patients with AITD,and 105 were patients with non-AITD.Questionnaires were designed to determine the general state of the patients,the size,shape and texture of the thyroid,the urinary concentration of iodine,the function of thyroid and the autoantibody of thyroid.The data were processed by SPSS12.0.Results The mean urinary concentrations of iodine in patients with GD,with HT,and the control group were 212?g/L,245.4?g/L,and 197.8?g/L respectively,which were statistically different.In the HT group,wich different urinary concentrations of iodine,there were no statistical difference of TGAb,TMAb,and HS-TSH.Conclusion Excessive in-take of dietary iodine may be related with AITD.

The arteries of the foot in one hundred Chinese adult specimens were dissected and examined. 1. The dorsalis pedis artery was absent in 4%, and it originated from an abnormal origin in 5%, its course and relationship with the tendon of the extensor hallucis longus and deep peroneal nerve were also described. 2. The anterior medial and anterior lateral malleolar arteries originated more commonly at the level of the ankle joint, and sometimes they may originate from the dorsalis pedis artery. 3. The origin and number of the medial tarsal artery were variable, but that of the lateral tarsal artery were more constant. 4. The arcuate artery was present in 35%, but only 17% was typical in form, from which the 2nd-4th dorsal metatarsal arteries were giving off. 5. The sources of the dorsal metatarsal arteries were the most variable. The first dorsal metatarsal arteries which arose from dorsal or plantar aspect were similar in percentages. The 2nd-4th dorsal metatarsal arteries often originated from the plantar aspect, but it was not uncommon that they came equally from dorsal and plantar aspects. 6. The artery of the tarsal sinus was usually present, it may be divided into two categories, namely the proximal and the distal artery, with their distinct origins and courses. 7. The arterial trunks in the sole of the foot were more constant. The posterior tibial artery usually branched into its two main branches near the lower border of the laciniate ligament. 8. The lateral plantar artery was greater than the medial in 82%. And 71% of the plantar arch was formed chiefly by the deep plantar branch of the dorsalis pedis artery. 9. The plantar metatarsal arteries originated usually from the plantar arch, sometimes the neighbouring arteries may have a common trunk. The course of the Ist-3rd plantar metatarsal arteries was constant, but that of the 4th may be variable. Finally, some questions about the arteries of the foot, present in previous literatures, were briefly discussed.

The diaphyseal nutrient foramina of 123 pairs of radius and 112 pairs of ulna from local Chinese adult skeleton collection have been observed. Their length, diameter and circumference were measured.The nutrient foramina on the shaft of radius, in longitudinal direction, located near the junction of the upper and middle thirds, and those of ulna located a little lower.In horizontal direction, the nutrient foramina chiefly concentrated on the anterior surface. But there were more foramina situated on the interosseous crest or posterior surface on radius than that on ulna.100 cases of nutrient artery to radius and ulna have been dissected on preserved cadavers. The length, diameter and distance from the origin of the artery to the level of elbow joint have been measured. The nutrient arteries to radius and ulna may have. various origins. They mostly arise from anterior interosseous, common interosseous, ulnar, ulnar recurrent and rarely from radial, median or dorsal interosseous arteries.The course and distribution of the nutrient arteries in the bone marrow cavity were examined on X-ray films prepared from injected radio-opaque specimens.

The facial, retromandibular and external jugular veins of the neck were studied in a total of 230 Chinese cadavers.1. The external jugular vein can be divided into six types and fourteen subtypes. Type Ⅰ(40.22％) and type Ⅲ (29.13％) occurred more frequently in this series.2. The facial vein drains into the external jugular vein in 41.09％. It drains directly or indirectly into the internal jugular vein in 43.91％.3. The anterior branch of the retromandibular vein usually drains into the internal jugular vein and it runs through the space deep to the posterior, belly of the digastric and the stylohyoid muscles in 83.70％.4. The presence of the so called common facial vein occurred only in 29.13％.5. The external jugular vein often drains into the subclavian vein. It appears in 46.57％ in our observation.6. The external jugular vein crosses the inferior belly of the omohyoid muscle, when it runs downwards in the lower part of the external cervical triangle. It usually lies superficial to the omohyoid in 66.16％, deep to it in 26.35％.

The projection area of the volar surface of the human hand was estimated on 52 young Chinese adults(26 males and 26 females.)ranging in age from 18 to 31. The average projection area of the volar surface of the hand was 145.20 square centimetres.It occupied 0.93％ of the calculated body surface.The area of the palm was 86.69 square centimetres, amounting to 59.70％ of the volar surface of the whole hand. All dimensions of different parts of the hand of males were larger than those of females. There was no difference between the right and left hands of both sexes. The coefficient of correlation among the body length, body weight, length and width of the hand, surface area of the whole body with the projection area of the volar surface of the hand was calculated. All showed close correlation. The regression of the estimation of the projection area of the volar surface of the hand with hand length and hand width was established. It is therefore to be assumed that the area of the volar surface of the hand calculated as one per cent of the body area, as it is often used in surgical examina- tions, seems to be a little higher than its real area(0.93％.
